onSaveInstanceState() not working

I have a form. Here, the user fills in details like event name, description, location etc. To select the location, I have set a button. When I click on the button, I am taken to another page/intent. I select the location from there, and the location data is passed back to my original intent correctly. But the thing is, the data in the other fields like event, description etc. that users filled in are lost. I posted thisquestion before and tried those out. I referred to thistoo and tried using onSaveInstanceState like this:

private static final String ENAME = "ENAME";
private static final String DESC = "DESC";
private static final String SDATE = "SDATE";
private static final String EDATE = "EDATE";
private static final String STIME = "STIME";
private static final String ETIME = "ETIME";

@Override
public void onSaveInstanceState(Bundle savedInstanceState) {
    final String name = etename.getText().toString();
    savedInstanceState.putString(ENAME, name);
    final String des = etdes.getText().toString();
    savedInstanceState.putString(DESC, des);
    final String sdt = StartDate.getText().toString();
    savedInstanceState.putString(SDATE, sdt);
    final String edt = EndDate.getText().toString();
    savedInstanceState.putString(EDATE, edt);
    final String stm = StartTime.getText().toString();
    savedInstanceState.putString(STIME, stm);
    final String etm = EndTime.getText().toString();
    savedInstanceState.putString(ETIME, etm);

    // Put (save) other values into the outState bundle...

    super.onSaveInstanceState(savedInstanceState);
}

I have that function before the onCreate(); And here is my onCreate();

protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.eventcreaten);

    etename = (EditText) findViewById(R.id.etename);
    etdes = (EditText) findViewById(R.id.etdes);
    StartDate = (EditText) findViewById(R.id.etstartdate1);
    EndDate = (EditText) findViewById(R.id.etenddate1);
    btnCreateEvent = (Button) findViewById(R.id.btncreate);
    tvd2 = (TextView) findViewById (R.id.tvd2);
    tved2 = (TextView) findViewById (R.id.tved2);
    tvg = (TextView) findViewById (R.id.tvg);
    StartTime = (EditText) findViewById (R.id.etstartt1);
    EndTime = (EditText) findViewById (R.id.etendt1);


    if (savedInstanceState != null) {
        final String name = savedInstanceState.getString(ENAME, "");
        etename.setText(name);
        final String des = savedInstanceState.getString(DESC, "");
        etdes.setText(des);
        final String sdt = savedInstanceState.getString(SDATE, "");
        StartDate.setText(sdt);
        final String edt = savedInstanceState.getString(EDATE, "");
        EndDate.setText(edt);
        final String stm = savedInstanceState.getString(STIME, "");
        StartTime.setText(stm);
        final String etm = savedInstanceState.getString(ETIME, "");
        EndTime.setText(etm);
    } else {
        // No saved values to restore
    }

And it doesn't work. Can someone please point out why?
